Thief

Thief, a 2014 stealth title, proves remarkably scalable on the Intel Core i5-12400F and NVIDIA GeForce RTX 5070 pairing, with benchmark data showing that the Ultra preset provides the most visually complete experience while only marginally sacrificing frame rate compared to High settings. The measured results indicate this combination is far more GPU-bound than CPU-bound across all tested resolutions, making it an excellent match for this game.

Settings Recommendations

The Ultra preset delivers the best experience for this combo, as the data shows a negligible performance cost over High settings across all resolutions. At 1920x1080, Ultra achieves 137.6 FPS compared to High's 140.6 FPS, a difference of only 3 FPS that is imperceptible in actual gameplay. The pattern holds at 2560x1440, where Ultra runs at 106.2 FPS versus High's 108.3 FPS, again a minimal 2.1 FPS penalty. Even at 3840x2160, the gap narrows to just 1.4 FPS (62.2 vs 63.6), making Ultra the clear choice for maximum visual fidelity without sacrificing smoothness.

Medium settings offer a middle ground, providing 157.4 FPS at 1080p, 135.5 FPS at 1440p, and 82.2 FPS at 4K. However, given that Ultra maintains frame rates well above 60 FPS even at 4K, there is no compelling reason to drop below High for competitive play. Low settings, while producing the highest frame rates (171.7 FPS at 1080p, 150.2 FPS at 1440p, 109.5 FPS at 4K), abandon the game's atmospheric stealth visuals for marginal gains that the hardware does not require. The data suggests that Ultra is the optimal preset, as it keeps the game's immersive lighting and shadow effects intact while staying comfortably within playable frame rate territory at every resolution tested.

GPU Role

The NVIDIA GeForce RTX 5070 is the dominant component in this pairing for Thief, as evidenced by the frame rate scaling patterns. The GPU's 12 GB of GDDR7 memory on a 192-bit bus provides 672.0 GB/s of bandwidth, which is more than sufficient for a 2014 title's texture and geometry demands. The RTX 5070's boost clock of 2512 MHz, built on the Blackwell 2.0 architecture with a 5 nm process, delivers 30.87 TFLOPS of FP32 compute, ensuring that even the most demanding scenes in Thief are rendered with ample headroom.

The GPU's performance percentile of 83 vs all GPUs places it well above average, and its average benchmark score of 41687 sits nearly even with the NVIDIA GeForce RTX 3090, which shows a deltaPct of 0.6. This near-parity with a previous-generation flagship explains why the RTX 5070 handles Thief's Ultra settings with such ease. The pixel rate of 201.0 GPixel/s and texture rate of 482.3 GTexel/s are particularly relevant for a game that relies heavily on environmental detail and shadow rendering, both of which are computationally intensive for the rasterization pipeline.

Interestingly, the GPU's DirectX 11 passmark score of 277 and DirectX 12 score of 108 suggest that Thief's engine, which predates modern API overhead, benefits more from raw rasterization throughput than from advanced feature sets. The RTX 5070's 80 ROPs and 192 TMUs provide the necessary fill rates to maintain high frame rates even at 4K Ultra, where the measured 62.2 FPS indicates the GPU is working near its limits but still delivering a playable experience.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a classic GPU-bound scenario with some CPU influence at lower resolutions. At Ultra settings, the FPS drops from 137.6 at 1920x1080 to 106.2 at 2560x1440 (a 22.8% reduction), then to 62.2 at 3840x2160 (a 41.4% reduction from 1440p). This steepening decline as resolution increases is the hallmark of a GPU-limited workload, where the RTX 5070's rendering throughput becomes the bottleneck.

However, the scaling is not perfectly linear, which indicates some CPU headroom being consumed at 1080p. The jump from 1080p to 1440p costs 31.4 FPS on Ultra, while the jump from 1440p to 4K costs 44 FPS. If the system were purely GPU-bound, the percentage drops would be more consistent, but the data shows the CPU is still contributing meaningfully at lower resolutions, where the i5-12400F's 6 cores and 12 threads are sufficient to feed the GPU without becoming a limiting factor.

At Low settings, the scaling pattern shifts dramatically. The RTX 5070 produces 171.7 FPS at 1080p, 150.2 FPS at 1440p, and 109.5 FPS at 4K. The 1080p to 1440p drop of 21.5 FPS (12.5%) is smaller than at Ultra, suggesting that at Low settings, the CPU begins to play a larger role at 1080p, as the GPU has more headroom to render frames quickly but is constrained by the processor's ability to submit draw calls. This is consistent with the i5-12400F's single-thread score of 909 in 3dmark, which is solid but not exceptional for a high-refresh-rate scenario.

How This Combo Ranks

The Intel Core i5-12400F + NVIDIA GeForce RTX 5070 combination ranks 349th out of 1642 tested combos in Thief, placing it in the top 21.3% of all configurations. This percentile positioning is strong, though not elite, which is expected given that Thief is a 2014 title that does not fully utilize modern multi-threaded CPUs or current-generation GPU features. The combo's rank is likely held back by the CPU's relatively modest 77th percentile vs all CPUs, while the GPU's 83rd percentile is more impressive.

The combination outperforms many newer, more expensive setups because Thief's engine favors high single-thread performance and raw GPU throughput over core counts and advanced shading. The i5-12400F's Cinebench R23 single-core score of 2332 and multi-core score of 16518 provide a balanced foundation, while the RTX 5070's average benchmark score of 41687 (compared to the RTX 3090's deltaPct of 0.6) ensures that the GPU is never the weak link. This pairing's rank of 349 suggests that users with this hardware are getting near-flagship-level performance in this specific game, even if the components are not top-tier across all workloads.

CPU Role

The Intel Core i5-12400F plays a supporting but essential role in this Thief configuration. With 6 cores and 12 threads running at a base clock of 2.50 GHz and a boost clock of 4.40 GHz, the CPU provides enough processing power to keep the RTX 5070 fed without becoming a bottleneck at standard gaming resolutions. The 18 MB of shared L3 cache and 1.25 MB per-core L2 cache help reduce memory latency, which is crucial for a game that streams environments and AI logic.

The CPU's benchmark results show a well-rounded profile: a 3dmark single-thread score of 909 and a max-thread score of 5912 indicate that the i5-12400F can handle both lightly-threaded game logic and more demanding background tasks. Its Cinebench R20 multi-core score of 6937 and single-core score of 979 place it in the 77th percentile vs all CPUs, with nearest rivals including the Intel Core i7-8700K (deltaPct 0.1) and AMD Ryzen 5 7533HS (deltaPct -0.7). This near-parity with older high-end CPUs and newer mid-range parts means the i5-12400F is perfectly adequate for Thief's CPU demands.

The data shows that the CPU's role becomes more pronounced at lower settings and resolutions. At 1080p Low, the system achieves 171.7 FPS, which approaches the CPU's practical limit for frame generation in this engine. The 3dmark 2-thread score of 1699 and 4-thread score of 3067 suggest that Thief, which likely uses two to four threads for its core simulation, is well-served by this processor's high boost clock and efficient Alder Lake architecture.

Measured FPS Breakdown

At 1920x1080, the combo delivers 171.7 FPS on Low, 157.4 FPS on Medium, 140.6 FPS on High, and 137.6 FPS on Ultra. These numbers show that even at the highest preset, the system maintains frame rates well above the 144 Hz refresh rate common on modern monitors, with the gap between Low and Ultra being 34.1 FPS (19.9% reduction).

Moving to 2560x1440, the measured averages are 150.2 FPS on Low, 135.5 FPS on Medium, 108.3 FPS on High, and 106.2 FPS on Ultra. The 1440p results indicate that the RTX 5070 still has substantial headroom, as even Ultra settings produce over 100 FPS, which is smooth for most gaming scenarios. The drop from 1080p to 1440p at Ultra is 31.4 FPS, representing a 22.8% decrease.

At 3840x2160, the system achieves 109.5 FPS on Low, 82.2 FPS on Medium, 63.6 FPS on High, and 62.2 FPS on Ultra. The 4K Ultra result of 62.2 FPS is just above the 60 FPS threshold for smooth gameplay, while the High preset's 63.6 FPS offers nearly identical performance. The scaling from 1440p to 4K at Ultra is a 44 FPS drop (41.4%), which is the steepest decline in the entire dataset, confirming that the GPU is the primary limiter at this resolution. The Low preset at 4K still delivers 109.5 FPS, showing that the RTX 5070's 12 GB VRAM and 672.0 GB/s bandwidth are not constrained by memory capacity even at high pixel counts.
